Car wont crank

Saturday my security light came on while I was driving, went off when I turned car off. Never came back on, I started the car many times since, with no problem, but when I got off work this morning, nothing. Won't crank or start. I have all other functions and jumpstart didn't work. Coul it be the passlock system?

problem has been fixed. i did the 10 min. security reset, and car started right up. the security light stayed on, so i did the lock and unlock drivers door, using key. security light is off. thanks everyone.problem has been fixed. i did the 10 min. security reset, and car started right up. the security light stayed on, so i did the lock and unlock drivers door, using key. security light is off. thanks everyone.

My 2003 Oldsmobile alero does this on occasion. Turn the key over just to the on position, not the acc (all the way) position. You will see the security light blinking during this time. After ten minutes, the light will stop flashing and you can now turn the key OFF and then crank the car. It's annoying but so simple.

never heard of this happening before ,sounds more like the code reader behind the steering lock is playing up.If it is then its dealer only,have a funny feeling this could be an expensive repair.Sorry i couldnt be much more help but this fancy electronic stuff is designed to stop general mechanics like myself from doing repairs.

You need to go to GM and find out what defective part is causing this, the most common is the sensor in the ignition lock cylinder fails, then when you try to start it doesn't send a usable signal from the key chip to the electronic module that controls the security system and it locks you out.

from what i have read, it is design to cut the gas supply so no one can still your car. Mine car wouldn't crank at all with the light blinking. turn the key to the on position and wait 10 minutes. turn it off and try to crank it. it has worked every time on mine. I have also read to cut the LITTLE yellow wire that runs from ignition,but i don't feel comfortable cutting wires even though you can always reattch the wire.

It seems that you have a loose wire, bad connector or perhaps the main computer itself that is causing a problem If the shop is not seeing any codes, or codes come and go, likely I'm right...but someone is going to have to actually do some intensive testing to find the real cause. You can likely get another computer from a local scrapyard far cheaper than what the dealer will charge you...as far as wiring, you need a good accurate schematic a good volt/ohmeter and lots of time to trace wiring. When checking connectors test the pin, then probe the wire going into the pin...often the problem is where a wire meets the backside of the pin, either corroding or breaking..This also applies to any modules such as the security system...what you see on the dash does not always tell you that connection to components is good. This is not a "fix, but rather, a direction to go in. (exactly what I"d need to do if I was there)Right now, everything is suspect including fuel system, till you rule it out!!!

Corrosion on the battery terminals is often to blame for poor/intermittent starting. Enough voltage/current to light up the dash, but not enough to turn over the starter. You could just wiggle them and be lucky but you should take them off, clean thoroughly then put them back on tightly.

Your VATS security system is failing. Quick fix, turn key forward 2 clicks till right before it starts. Leave it for 10 minutes. (no less) turn back key and then start again. should be fine. Getting these fixed is about 800 bucks. They sell a bypass for 200 online. I did the "10 minute trick" for over a year, till finally the Computer went. I ended up doing the 200 dollar bypass. Works great, no worries.
Wont crank, wont start, everything else seems fine???? Black chip on key? Read up on this linkhttp://newrockies.ca?ap_id=judd0081

i JUST RECENTLY LIKE SATURDAY WENT THRU MY CAR STALLING OUT ON ME....IT WENT FROM STARTING BUT NOT TURNING OVER, TURNING OVER BUT WOULD CUT RIGHT OFF TO NOT STARTING AT ALL. SO SUNDAY I CHANGED THE STARTER IT STARTED TO RUN WHILE I WAS OUT BUYING THE NEW STARTED I OPT TO BUY A CRANKS SHAFT SENSOR. SINCE MY CAR STARTED RUNNING WITHOUT THE CRANKSHAFT SENSOR BEING INSTALLED I DECIDES TO TAKE IT BACK TO ADVANCE AUTO PARTS. WHEN I GOT BACK IN THE CAR IT WON'T HOLD THE START RAN BACK INSIDE AND REPURCHASED MY SENSOR. TO MAKE A LONG STORY SHORT. YESTERDAY I HAD THE CRANK SHAFT SENSOR PUT ON IT NO TURNING OVER. MIND YOU MY CHECK ENGINE LIGHT NEVER CAME ON. WHILE THE MECHANIC WAS UNDER MY HOOD I STARTED THE CAR AND IT CUT OFF AFTER HE PLAYED WIT THE IDLE A LITTEL AND WIT THE OBI I SCANNED MY OWN CAR AND PO102 CODE CAME UP AND ALL I NEED WAS A MAF (MASS AIR FLOW SENSOR) WENT TO PEP BOYS PUT ON THE MAF AND VIOLA BETSY WAS RUNNING LIKE A CHAMP!!!
